Abstract:
This work reports a highly sensitive Fe doped ZnO nanoneedles based gas sensor for detection at low concentrations. Pure and Fe doped ZnO were synthesized via a hydrothermal method and spray-coated onto an alumina substrates. The sensing properties were investigated under different temperatures and concentrations. Fe doping significantly increased the sensing performance of ZnO nanoneedles. The 5 at% Fe doped sensor showed the best response to isopropanol and the optimal working temperature is 275oC. The sensor showed a high response to 250 ppb isopropanol, together with high stability under different humidity levels.
